Example: Reading Function Values, Intercepts, Domain, and Range from a Graph (Variant 1)

A service technician uses a function $C(h)$ to calculate the total repair cost based on the number of hours ($h$) worked. To analyze the billing data, the technician views the function's graph. Match each mathematical term with its correct description in the context of this graph.

In the graph of a mathematical function $f$, the $y$-coordinate of any point on the graph can be represented by the function notation $f(x)$.

A project manager uses a function $C(x)$ to model the total production cost of a specific part, where $x$ represents the number of units produced. When the manager looks at the graph of this function on a coordinate plane, what does the value $C(x)$ represent for any point $(x, C(x))$ on the graph?

Visualizing Industrial Data

A business analyst is using a mathematical function to model a company's weekly shipping costs. When this function is plotted on a coordinate system, the resulting graph serves as a visual representation of all the function's ordered ____, which can be written in the form $(x, f(x))$ to show the relationship between a specific week and its cost.
